VCOFan Voltage-Controlled Fan Oscillator

Gieskes VCOFan

VCOFan from Gieskes is nearly exactly what it says it is—an electronic fan, typically meant for keeping electronics cool, now implemented as an ultra-cool oscillation source for Eurorack rigs. A revolution in oscillator design, the VCOFan uses the spinning speed of its eponymous component to generate oscillating signals at varying speeds. In this VCOFan1f revision, the fan can be manually or CV controlled to produce a wide range of pitches from nasally high tones to low drones. Onboard is also an integrated volume control which can be used as a direct VCA to create swelling shapes, or even triggered to create percussive plucks. If you're looking for a way to ensure you have the coolest Eurorack system around, don't miss VCOFan from Gieskes.
